Reliable Electrical Switching for Industrial Automation
Electromagnetic power relays such as the Finder 65.61.8.110.4000 allow an electrical control signal to operate separate load circuits. When the 110 V AC coil is energised, the normally open contact closes and the normally closed contact opens. When the coil supply is removed, both contacts return to their original states.
This switching arrangement makes the relay suitable for control systems requiring complementary switching functions, such as enabling one circuit while disabling another. The Finder 65 Series is designed for industrial equipment manufacturers and automation engineers who require dependable electromagnetic switching, robust contact construction and straightforward PCB integration.
The 65.61.8.110.4000 combines a practical PCB-mounted format with silver tin oxide contacts and a 110 V AC operating coil. These characteristics make it suitable for electrical control assemblies, industrial heating equipment and automated machinery where reliable relay operation is essential.
